Thomastik Infeld Spirocore violin strings are a warm, projecting set of strings made of multi-wire, spiraled steel core (similar to a rope core). Known for their versatility between arco and pizzicato, Spirocore strings offer a dark, warm sound with strong projection. These strings are designed for a more pliable touch under the fingers, while remaining somewhat responsive and focused. Spirocore strings are similar to Thomastik Infeld Superflexible strings in warmth, with greater clarity of sound.
